Star-shaped stack system and method thereof

Abstract

The invention discloses a star-shaped stack system, which comprises a master domain and a star-shaped stack topology which consists of a plurality of slave domains. The master domain consists of one or more than one of stack equipment, wherein the stack equipment in the master domain are interconnected by a stack opening of the master domain; master domain has a plurality of groups of stack openings of the slave domains, wherein one or more than one of the stack equipment hung under the each group of the stack openings of the slave domains forms into one slave domain; the stack equipment in the main domain and the stack equipment hung in the slave domain forms into one stack domain, wherein the stack equipment of the each stack domain carries out topology collection in the stack domain, and completes the stack process of the equipment according to sequential main domain topological convergence, slave domain topological convergence and whole topological convergence. The invention effectively improves the band width of stack links, improves the connection reliability between the master equipment and the slave equipment, and increases the amount of stack members.

Description

technical field [0001] The present invention relates to the communication field, in particular to a star stacking system and method. Background technique [0002] Stacking refers to combining more than one switch to work together to provide as many ports as possible in a limited space. Ethernet switch stacking technology can interconnect multiple switches together to form a distributed switching architecture and operate as a logical switching entity. [0003] From a management and configuration point of view, a distributed switching architecture looks like a switching device; from a performance point of view, each switch in the distributed switching Layer traffic communication services make local forwarding decisions. [0004] Support stacking Multiple switching devices can be connected to each other to form a "joint device". We call this "joint device" a Stacking (stack), and each device that makes up the Stacking is called a Slot (member). After multiple Slots form Stac...

Problems solved by technology

[0007] The stack links between the stack devices in the ring stack need to carry the traffic of multiple stack members. Therefore, the traffic carrying capacity of the stack links becomes the traffic forwarding bottleneck; The time delay is large; the addition and exit of ring stack members will cause the entire stack to re-collect and calculate the topology. During the re-calculation process, the normal sending and receiving of service packets cannot be guaranteed.
